Topic: Leadscrew nut material (Read 5856 times)

What are the preferences for material for making leadscrew nuts from?I'd like to make new one for my Ajax mill's Y axis which has been bastardised.....Its been cut with a BSW thread which Im sure isnt original....

The material used looks like Phos B.....but to buy a piece the same size is going to be a kings ransom....

Norman,The issue is the block that forms the nut is about 1" thick and measures approx 1-3/4 square....

It looks like it has been fashioned from an offcut or scrap piece of phos-b....then a hole drilled and threaded 3/4 bsw....I dont believe the thread is original....so my plan is to make a new lead screw and nut with a finer thread....either bsf or bsc....

John, I have a length of cored PB which has been knocking around the workshop for years, with some work on the mill you should be able to produce your required size. I'm happy to cut a length off and post it if you wish for postage costs only.
